For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless.
After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases. These are molecules with millions of hydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped.
Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago: water vapor, ammonia, carbon dioxide, methane, and hydrogen.
Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After seven days, the water that the gases had been bubbling through had turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids-the very kind of molecules found in all living things.

When I was growing up, I was embarrassed to be seen with my father. He was badly crippled (跛脚), and when we would walk together, his hand on my arm for balance, people would stare, I would be ashamed of the unwanted attention. If ever noticed or bothered, he never let on.
It was difficult to walk together—and because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace. I will try to follow you.”
Our usual walk was to or from the subway, which was how he got to work. He went to work sick, and even in bad weather. He almost never missed a day, and would make it to the office even if others could not. It was a matter of pride for him.
When snow or ice was on the ground, it was impossible for him to walk, even with help... Such times my sister or I would pull him through the streets of Brooklyn, N.Y., on a child’s sleigh to the subway entrance. Once there, he would try to grasp handrail until he reached the lower steps that the warmer tunnel air kept ice free. In Manhattan the subway station was the basement of his office building, and he would not have to go outside again until we met him in Brooklyn on his way home.
When I think of it now, I am surprised at how much courage it must have taken for a grown man to suffer from shame and disability. And I am also surprised at how he did it—without bitterness or complaint.
He never talked about himself as an object of pity, not did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him.
Now that I am older, I believe that is a proper standard by which to judge people, even though I still don’t know exactly what a “good heart” is. But I know the times I don’t have one myself.
He has been away for many years now, but I think of him often. I wonder if he sensed my reluctance to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I complain about my troubles, when I am envious of another’s good fortune, when I don’t have a “good heart”.
How did the man treat his father when he was young?
A. He helped his father happily.
B. He never helped his father.
C. He helped his father, but not very happily.
D. He only helped his father take a walk after supper.
As a disabled man, his father____.
A. didn’t work very hard
B. didn’t go to work from time to time
C. hated those who had good fortune
D. was happy and satisfied, and never lost hope
What does the underlined word “reluctance” mean in the article? It means ____.
A. anger B. sadness C. happiness D. unwillingness
How did the father get to work usually?
A. By subway. B. By bus. C. By wheelchair. D. By bike.
